Which of these kinematic equations is in the correct chronological order for describing the motion of an object under constant acceleration?

If a Tesla Model S P100D in 'Ludicrous mode' is pushed to its limit, the first $3.0\text{ s}$ of acceleration can be modeled as

What acceleration would be needed to achieve the same speed in the same time at constant acceleration? Give your answer as a multiple of $g$.

Consider the street pattern shown in Fig. 2–51. Each intersection has a traffic signal, and the speed limit is 40 km/h. Suppose you are driving from the west at the speed limit. When you are 10.0 m from the first intersection, all the lights turn green. The lights are green for 13.0 s each. Another car was stopped at the first light when all the lights turned green. It can accelerate at the rate of 2.00 m/s² to the speed limit. Can the second car make it through all three lights without stopping? By how many seconds would it make it, or not make it?                                                                                                                                       

Show that $\bar{v}=(v+v_0)/2$ (see Eq. 2–12d) is not valid when the acceleration $a=A+Bt$, where A and B are non-zero constants.
